SAFE WORKING

SAFE TRANSPORTATION

• When towing a chipper the maximum speed limit is 60
mph (96 km/h).
• On rough or bumpy road surfaces reduce speed
accordingly to protect your machine from unnecessary
vibration.
• When towing off road be aware of objects that may catch
the chipper undergear.
• When towing off road ensure inclination is not excessive.
• Avoid excessively pot holed ground.
• When reversing the chipper the short wheel base will
react quickly to steering.
• Always check the discharge is tight before moving.
• Keep tyre pressures inflated to 3.4 bar or 50 psi.

HITCHING ONTO THE TOW BALL

• Check ball head is well greased.
• Wind jockey wheel assembly anticlockwise until the tow
head is above the height of the ball hitch on the vehicle.
• Reverse vehicle so the ball hitch is directly below
the tow head.
• Attach breakaway cable to a strong point on the vehicle,
not the ball hitch.
• Grasp handle on tow head and push back catch with
thumb.
• Wind jockey wheel assembly clockwise, to lower the tow
head onto the ball hitch.
• Release handle and continue to wind jockey wheel
clockwise. The tow head should snap into place on the
ball hitch. If it doesn't, repeat previous 2 steps.

UNHITCHING THE CHIPPER

• Ensure the chipper will not roll away after being
disconnected from the vehicle.
• Disconnect the electrical cable from the vehicle socket
and stow in the dock provided on the chassis when not
in use.
• Release breakaway cable and stow in the dock provided
on the chassis when not in use.
• Release the jockey wheel assembly clamp.
• Lower the jockey wheel assembly fully.
• Retighten the jockey wheel assembly clamp.

STABILISING THE CHIPPER

should be released and the prop stand and jockey
wheel stored in the towing position (a).

• Check wheel nuts are
tightened to 65 lb ft (88
Nm).
• Clear loose chippings
and debris from the
machine before
departing.
• Ensure feed funnel is closed and the catch is properly
engaged before departing.
• NEVER transport any items in feed funnel.
• Ensure tow hitch lock mechanism is locked before
transporting.
• Wind jockey wheel up until fully retracted and the jockey
wheel frame is seated in its notch on the stem. The
chipper weight should be fully on the vehicle.
• Check jockey wheel handle is secure before
transportation. Do not overtighten jockey wheel handle.
• Release jockey wheel clamp and slide the jockey
wheel assembly fully up.
• Tighten clamp on jockey wheel assembly.
• Connect electrical plug to socket on rear of towing vehicle
and check operation of all the trailer and vehicle lights.
• The chipper is now properly attached to the vehicle.
• Wind the jockey wheel assembly anticlockwise until it
starts to take the weight of the chipper.
• Grasp the handle and release the catch with your
thumb.
• Continue to wind the jockey wheel anticlockwise. This
should lift the tow head clear of the ball hitch.
• Drive the vehicle clear of the chipper.
• Wind the jockey wheel assembly to a suitable point
where the chipper is level. Do not overtighten jockey
wheel handle.
• The chipper is now fully detached from the vehicle.
When the chipper is unhitched it should be level and made
secure before starting work by applying the handbrake and
lowering the prop stand and jockey wheel (b).
During unhitched storage the chipper must be level with
the discharge chute pointing towards the towhead.
